SPECIFICATION forming part of Letters Patent No. 295,853, dated Il/Zarch25, 1884. Application filed November 8, 1883. (No model.)

To (LZZ whom it may concern.-

Be it known that I, IRA R. BEAM, of Dryden, in the county of TompkinsandState of New York, have invented a new and ImprovedEngraving-Machine, of which the following is a full, clear, and exactdescription. I

The object ofmy invention is to provide a simple and efficient machinefor engraving j ewelry, watches, plate, and other goods of the prowidearticles of various forms and sizes to be readily plates 6, under sideof plate a: at the ends of applied to the machine for being engraved;also with an improved construction and arrangement of theengraving-tool, and the apparatus for workingit, and provement in theapparatus for holding the copy, from which the movements of theengraving-tool are to be directed by a style, all as hereinafter fullydescribed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in allthe figures.

Figure 1 is a plan view of myimproved engraving-machine, and Fig. 2 ispartly a side elevation and partly a sectional elevation.

The bed-frame of the machine consists of the two plates a and I), set onlegs (1 or other approved supports, and connected by the crosswhich arebolted at one end to the said plate by bolts f, and at the other endsare bolted to the top of plate I) by bolts 9, these bolts passingthrough slots h of said cross-plates, which slots are employed forenabling the plates or b to be set nearer together or farther apart, asmay be required; and also for enabling vise or clamp holding bars ofdifferent forms to be bolted to said cross-bars for holding differentsizes and forms of work to the engravingtool The bolts f and g aresecured by thumbnuts, to enable the bolts to be readily fastened andunfastened. At the middle and outer edge of plate a a slotted uprightsupport, j, is

mounted for the support of the head It, to which so head the joint Z ofthe parallel frame for workingthe engravingtool is hinged by the pin m,said being verticallyadjustable along the veralso with an imtical grooveby the shifting-bolt 0, attached to the head and extending through theslot of the support and being secured by a thumb-nut,

10. The head is has a tongue, q, fitting in the groove of the supportfor being held firmly. To the joint Z of said tool-carrying frame, the

style joint s, carrying the tracing-style t, is

staif; of the engraving-tool h is fitted, and all the joints of the saidframe are perforated with numerous holes to enlarge or control the di-'mensions of the frame by shifting the pinsw and x, and adjusting thejoints according as the scale of the engraving to be made is to beincreased or diminished. Under the point of the tracing'style the tablect, for holding the design-plates b, to be engraved by the tool 72, islocated, said table being pivoted at c to a lever, f, jointed at g to anarm, d, jointed at e to the under side of plate I) at its middle orthereabout. Thelever f extends to one end of table a, where it isprovided witha holding pawl, h, which engages with notches i in the endof the table to hold the lever when swung toward plate I), to bind theplates 1), having the design to be copied between flangej of the .by atubular pivotstud, 1, through which the l while being traced by thestyle tto guide the engraving-tool for reproducing the design on thearticle to be engraved. The work Z is to be held under theengraving-tool h by any approved form of vise, which is to be attachedto one or more slotted bars, m, supported by screws m on other slottedbars, nf, which are supported by the plates a and b, which haveslot-holes 0 for the fastening-bolts p, by which and nuts i said bars aare secured, to enable them to be adjusted to suit the form and size ofthe vise or clamp, of which different forms and sizes will be used,according to the form and size of the article to be engraved. The viserepresented in Figs. 1 and 2 consists of a rectangular frame, q,containing sliding jaws s and adj listing-screws it, said frame beingclamped onto the slotted bar in by the thumbscrew u,- but various otherforms of clamps or Vises may be used, for which the bars m and n will beshifted, as required. The engraving-tool h is set obliquely in the endof the bent arm '0 of the staff 2, so that the point of the tool restsin the aXis of the staff, to enable the staff to be turned for settingthe point of the tool in the direction in which it is to be moved, asthe direction changes in the form of the design being engraved Withoutthrowing the cutting-point out of said line, thus enabling anengraving-tool to be used in that form of machine, so as to cut in itsnatural way; and the staff is arranged in the tube y, and provided witha crank, w, on its upper end for turning it as the work progresses andthe direction changes. The staff is also made to slide up and down, sothat the tool may be made to cut uniform lines on oval work by pressingit down with the finger, and allowing it to be raised by the spring 00,according to the form of the surface being engraved. The cutter can, bythe same contrivance, be made to cut fine shadelines or heavy lines, aspreferred.

Different cutters and, forms of cutter-staffs will be employed,according to the nature of the work, some of the staffs being suitablybent, to engrave inside of rings and other articles. At (6 in Fig. 1, isshown a form of vise adapted for holding circular or elliptical work.Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent 1. The improved engravingmachine frame,consisting of plates a I), having leg or other supports, (1, andconnected by slotted crossbars a, the plate a, having the slottedupright support j for the tool-frame head 70, and the plate I), havingthe copy-table a, connected to it, all substantially as described.

2. In an engraving-machine, the combination, with the head 70, adjustably connected to its support, of the frames Z, pivoted to the headit, the frame 8, pivoted to frame Z, and the frames to n, pivotedtogether and to the frames 3 Z, respectively, the tool-staff z in thejoints of the frames at v, and the style it in the end of the frame 8,substantially as herein shown and described.

3. The adjustable vise q s t and slotted adjustable supporting-bars mand n, in combination with the bed-frame plates at b, and the paralleltool-frame and engraving-tool, substantially as described.

4. The table a, having flange j, and being pivoted on the lever f,connected by link d with the bed-plate b, and having the catchpawl h,said table also being arranged to clamp the copy-plates b against theedge of bed-plate b, and having notches Z for the holding-pawl,substantially as described.

5. In an engraving-machine, the combination, with the slotted plates ab, of the slotted bars a, adjustably attached to said plates a Z),

and the slotted plate m, for supporting adj ust-- ably a work-holdingvise, substantially as described.
